Wilson Seater Blank Question.

[Hoekight]

Any of you who have chambered a Wilson seater blank; how much head space is needed? I figure you could cause major problems if it weren’t deep enough by actually changing the shoulder on your brass. But didn’t figure you wanted too much either. 7-6.5!for reference. Thanks in advance.

I chamber them with a few thousandths clearance. If you do your own chamber work then you can use the headspace gage, if not I’d want several 3x fired cases to fit it.

Thank you. I am chambering it but didn’t know if using a headspace gauge would be enough clearance. For some reason I thought I read somewhere around 10 thousandths was needed.

I chamber with hs gage to ~+.001 so by giving the seat die a few thousandths or so you should be good but I’d think .010” would still work fine. Even at .010” there isn’t going to be much radial clearance for misalignment. If you go too far it’s easy enough to take a touch off the bottom.
